IMPROVEMENT IN FENCE-GATES.

Specification forming part of Letters Patent No.. 2 I 1,496, datedJanuary 21, 1879; application filed August 5, 1878. p

To all whom it may concern:

Be it known that I, ISAAC S. CORY, of Dalton, in the county of Wayne,State of Indiana, have invented certain new and useful Improvements inFence-Gates, of which the following is a description sufticientlyfull,clear, and exact to enable any person skilled in the art or science towhich my invention appertains to make and use the same, referencebeing-had to the accompanying drawing, forming a part of thisspecification, inwhich Figure 1 is a side elevation, showing the gate,and Fig. 2 a similar view showing it.

Likeletters of reference indicate corresponding parts in the difl'erentfigures of the drawmg.

My invention relates to that class of fencegates which are automatic orself-closin g; and consists in a novel construction and arrangement ofthe parts, as hereinafter more fully set forth and claimed, by which asimpler, cheaper, and more efi'ective device of this character isproduced than is now in ordinary use.

In the drawing, A represents the ground, and B O Dthe posts. The body ofthe gate proper consists of the end rails, E F, top rail, G, bottomrail, H, bars I J :r, and vertical center rail, K,

The top rail is elongated, as shown at L, and provided with a brace, M,the lower end of which is secured to the bottom of the rail F. A bar, N,has one of its ends attached to the top of the post D and its other tothe post 0, and is arranged in an inclined position, with its inner endthe lowest, as shown.

A bar, 0, is disposed in the upper section of the gate, being attachedto the rails E K F, and arranged in an inclined position correspondingwith the position of the bar N. The outer end of the bar 0 is extendedbeyond the rail F, as shown in Fig. 2, and provided with thedownwardly-projecting hook R, for preventing the escape or accidentaldisplacement of the sheave P.

A rigid catch, S, projects horizontally from the rail E, and is arrangedto intersect with the clasp or loop T on the post B.

Beneath the bar 0, and resting on the bar N, there is a roller orsheave, 1?, having an annu lar groove (not shown) in its periphery, in

which the lower edge of the bar 0 and upper edge of the bar N work inopening or closing the gate and there is also a sheave, Q, journaled inthe upper partof the brace M, against which the lower edge of the bar Nworks;

It will be obvious that the sheave 1? forms a friction-roller, whichtraverses the bar N'and supports the gate as it is opened and closed,the gate being prevented from sagging durin g the operation by the braceM and sheave Q.

The loop or clasp T is so arranged with respect to the catch S that theinclined lower edge, U, of the catch strikes the loop and slightlyraises the end of the gate as it is forced toward the post B in closing,so that when the gate is fully closed the catchand the clasp are keptinterlocked by the weight of the gate.

In the use of my improvement the gate may be readily opened by a person,either on horseback or on foot, by means of the handle V, after whichit'may be kept open at will by the clasp W, or left to close itself bygravitation, as desired.

It will be obvious that, in opening the gate, it will be raised fromtheground as the sheaves run up the bar N, as seen in Fig. 2, thus preventing in a great degree the interference of snow, ice, and othersubstances with its proper Working.

It will be understood that the post 0 is mortised vertically through thecenter, and acts as a guide to keep the gate in position. The traversingsheave P, instead of rolling on the bar N, may be journaled at or nearthe post 0, if preferred.

It will also be obvious that the handle V, rail K, clasp W, catch S, andbars I :20 may be omitted, if desired, without entirely departing fromthe spirit of my invention.

What I claim is- A sliding gate having a diagonal track-bar, O, incombination with the inclined supporting-bar N, fixed to posts (3 D,loose sheave l and fixed sheave Q, all constructed and open ated as setforth.
